Coconut oil extraction machine
Coconut oil extraction machine
Coconut oil extraction machine Coconut oil, also known as coconut oil, is obtained from coconut meat (dry) and is white or light yellow fat. Coconut meat (dry) contains 65%-74% oil and 4%-7% moisture. Coconut trees grow on islands in tropical areas or along the coast of the mainland. Compared with other fats and oils, coconut oil has great specificity. Coconut oil has a high saponification value and a low refractive index. This method can be used to identify whether coconut oil is mixed with other fats and can even be quantified. This change is mainly caused by Caused by the fatty acid composition of coconut oil. The fatty acid composition of coconut oil has a saturated content of more than 90%, but the melting point is only 24-27 degrees, which is due to the high carbonic acid content. This is also the reason why the Polenske value and Reichert-Meissl value are high. The fatty acid composition of coconut oil can also explain why complete hydrogenation has little effect on the melting point of coconut oil (45.1 degrees) Coconut oil is a white liquid in the tropics, and a butter-like solid in cold places; it has a special smell and has a fragrant smell when fresh. The specific gravity of the oil produced by the coconut oil extraction machine is 0.8354, the refractive index is 1.4295, the alkalinity value is 258, and the iodine value is 8.4 to 9.3. [Chemical composition] The oil content of the pulp is 60-65%. The oil contains 20% free fatty acids, 2% linoleic acid, 7% palmitic acid, 9% caprylic acid, 5% tallow wax, 10% caprylic acid, 2% oleic acid, and 45% lauric acid.

Peanut oil extraction production line
Peanut oil extraction production line
Peanut oil extraction production line The peanut oil in the peanut oil extraction production line is a non-dry vegetable oil (the iodine value is generally between 80 and 107). The specially processed peanut oil has an attractive and rich fragrance and is a kind of edible oil with high market value. Because it contains a higher proportion of unsaturated fatty acids (monounsaturated fatty acids account for 49%, polyunsaturated fatty acids account for 30%), especially the human essential fatty acid-arachidonic acid makes it have a higher nutritional value. In addition, peanut oil also has a lighter color, lower phospholipid content, higher smoke point and has better sensory indicators and cooking performance. Peanut kernels have high oil content, and there are three main oil-making processes: traditional pre-extracted leaching process, concentrated aromatic peanut oil process, cold-pressed peanut oil and peanut protein powder process. Considering that fragrant peanut oil is the main product in the peanut oil product consumer market, the market demand has great potential. At present, the oil production process mainly uses the fragrant peanut oil process, that is, the use of fried seed peanut kernels and hot air roasting: the total amount of 15%~20% peanuts The petals are sent to the hot air roaster, where the oil is heated to 180℃~200℃. The roasting temperature is the key factor for the aroma of peanut oil with strong aroma. The temperature is too low, the aroma is light; the temperature is too high, the oil is easy to gelatinize.
